hqlFilterStemsWhereClause

public boolean hqlFilterStemsWhereClause(edu.internet2.middleware.subject.Subject subject,
                                         HqlQuery hqlQuery,

                                         Set<Privilege> privInSet)

Description copied from interface: NamingResolver

for a stem query, check to make sure the subject can see the records (if filtering HQL, you can do the postHqlFilterGroups instead if you like). Note, this joins to tables, so the queries should probably be "distinct"

Specified by:

hqlFilterStemsWhereClause in interface NamingResolver

Overrides:

hqlFilterStemsWhereClause in class NamingResolverDecorator

Parameters:

subject - which needs view access to the groups

hql - is the select and part part (hql prefix)

stemColumn - is the name of the stem column to join to

privInSet - find a privilege which is in this set (e.g. for view, send all access privs). There are pre-canned sets in AccessAdapter

Returns:

if the query was changed

                                    Set<Privilege> privInSet)

Description copied from interface: NamingResolver

after HQL is run, filter stems. If you are filtering in HQL, then dont filter here

Specified by:

Overrides:

postHqlFilterStems in class NamingResolverDecorator
